ตอนที่ 4: เรโทรีเชิญสาวๆ ไปชมการแสดง Tsurezurenaru Ayatsuri Mugenan ปลุกแรงบันดาลใจให้ Plasmagica แต่งเพลงใหม่ ในขณะที่ Moa กังวลกับความลับของมนุษย์ต่างดาว

Retoree invites the girls to a performance by the popular enka band Tsurezurenaru Ayatsuri Mugenan, with the crowd becoming impressed by their unique culture and originality. Following the performance, after meeting the band members themselves, the girls feel they need to change their style in order to become more popular. However, Shingan Crimsonz's Rom reminds Plasmagica that the music is what's most important, so they instead decide to write a new song, their first since Cyan joined. Meanwhile, Moa, who is secretly an alien sent to investigate other worlds, grows concerned about her secret. (Source: Wikipedia)
